Subject: [PATCH 4.14 08/25] arm64: compat: Provide definition for COMPAT_SIGMINSTKSZ
Date: Fri, 2 Aug 2019 11:39:40 +0200 [thread overview]
Message-ID: <20190802092101.747842064@linuxfoundation.org> (raw)
In-Reply-To: <20190802092058.428079740@linuxfoundation.org>
From: Will Deacon <will.deacon@arm.com>
commit 24951465cbd279f60b1fdc2421b3694405bcff42 upstream.
arch/arm/ defines a SIGMINSTKSZ of 2k, so we should use the same value
for compat tasks.
